I wanted to paint my LR, DR & hallway and chose a color close to peasoup green (only something a tad brighter). It was my first time painting so I didn't test the paint first.
What I ended up with was a key lime green (very bright, very neon!). It would be a great interior color for a beach house but not for my place. I ended up putting on two coats thinking that it might make it a more saturated color. It looks better and more even but it's still way too bright!
Does anyone have any suggestions for toning down the color? Perhaps a muted top coat? It's a yellow-based green (rather than white-based green) if that helps.
Another option would be to use a ragging, or color-washing technique to get a different look without repainting completely. It just depends on whether you want the flat, seamless color look, or if you are open to texture and variations in color. In our kitchen we're doing a glazing of darker color over a lighter, paper bag color paint. It's one way of changing the look of the color underneath.
If you want solid color, go with Slickshift's advice.
